    Does lens cleaner w/ Isopropyl alcohol damage Blue Light, AR or Polarized lens?

    Hi, folks:

    Does lens spray cleaner that contains isopropyl alcohol do any harm on AR, blue-light coating and Polarized lens?

    It's a biodegradable solution.

    Thanks in advance.

    Never seen it happen, but one of many theories is that alcohol will "dry up" the AR coating. Not a very helpful answer, because I haven't found any facts to back it up.
    Also interested in the answer though, has anyone noticed any effects from long term use of these cleaners?

    Not alcohol but high concentrations of ammonia over long periods may.

    I recommend people use alcohol only occasionally, not for the lenses but for the frame materials that may dry out.

    That's a solid answer, thanks for the reply.

    So it's best that we use the alcohol-free AR lens cleaner instead of the ones come with alcohol?

    It depends on what you're trying to accomplish. I use alcohol for the final cleaning of every lens that leaves my lab to make sure the AR slick coat is evenly removed. Using alcohol once or twice in the lab process is one thing; you want to discourage your patients from using alcohol every time​ they clean their glasses.

    Yes, that makes sense.

    I think it depends on how often you use it. if you use it occasionally, I think it ok, no problem. But I have a problem. My cleaning cloth makes my glasses are scratched. Does anyoen have any suggestion about high quality cloth band? thanks in advance.

    I just recommend against IPA if at all possible. I have had it eat a frame once (literally, into pieces in my hands). It gave me PTSD regarding IPA.
